Flume Baselayer Bottoms - Women's


Made of the same material as our award winning Flume Baselayer (twice named the overall best hiking base layer by Field & Stream), these bottoms are made of a blend of Tencel (made from trees!) and spandex.  Tencel is naturally wicking, naturally odor resistant, thermo-regulating, and crazy comfortable. The perfect base layer for hiking, climbing, skiing, or just staying warm on a cool day.

Our Flume Baselayer Bottoms are hand-stitched in our Gorham, NH facility.

Most comfortable long underwear ever

Bought these for my wife and she loves them. She has worn them skiing four times now and swears by them. She no longer wears her old ones from Patagonia- and wants another pair!
